Ingredients You’ll Need
Core Ingredients
- Onions – 3 large yellow or sweet onions, thinly sliced.
- Olive oil + butter – for that perfect caramelization.
- Garlic – 3–4 cloves, minced.
- Dry white wine (optional) – adds depth.
- Beef broth – 4 cups, for authentic French onion flavor (use vegetable broth for vegetarian).
- Pasta – 12 oz. short pasta like rigatoni, penne, or rotini.
- Heavy cream – ½ cup, for silkiness (can sub half-and-half).
- Gruyère cheese – 1 cup shredded (mozzarella or Swiss also work).
- Parmesan cheese – ½ cup, for nutty richness.
- Fresh thyme – 1–2 sprigs (or ½ tsp dried thyme).
- Salt & black pepper – to taste.
Optional Garnishes
- Fresh parsley or thyme leaves.
- Extra cheese for topping.
Step-by-Step Instructions
1. Caramelize the Onions
- Heat olive oil and butter in a large pot or Dutch oven.
- Add sliced onions with a pinch of salt. Cook over medium-low heat for 25–30 minutes, stirring often, until deeply golden and jammy.
👉 Tip: Low and slow caramelization develops natural sweetness—don’t rush this step.
2. Build the Flavor Base
- Add garlic, cook 1 minute until fragrant.
- Deglaze with white wine, scraping up browned bits (if skipping wine, use a splash of broth).
3. Cook the Pasta in the Same Pot
- Stir in pasta, broth, thyme, and black pepper.
- Bring to a simmer, then cook until pasta is al dente (about 10–12 minutes). The pasta releases starch, thickening the sauce naturally.
4. Make It Creamy
- Reduce heat, stir in heavy cream and cheeses until melted and velvety.
- Adjust seasoning with salt and pepper.
5. Serve & Enjoy
- Remove thyme sprigs.
- Garnish with fresh herbs and extra cheese.
- Serve hot with a crisp salad or garlic bread.
Pro Cooking Tips
- Best onions: Yellow or Vidalia onions caramelize beautifully.
- Cheese choices: Gruyère is classic, but fontina or mozzarella add creaminess.
- Faster caramelization: Add a pinch of baking soda to onions (optional hack).
- Extra depth: A splash of balsamic vinegar boosts richness.
Variations to Try
- Vegan French Onion Pasta: Use olive oil, vegetable broth, cashew cream, and vegan cheese.
- Baked Version: Transfer to oven-safe dish, top with cheese, and broil until bubbly.
- Spicy Twist: Add chili flakes while cooking onions.
- Gluten-Free: Use gluten-free pasta and ensure broth is GF.
